Una asociación basada en redes de EII y cáncer colorrectal utilizando datos de proteómica

Área de la Ciencia:

• Oncology
• Gastroenterology
• Molecular Biology
• Bioinformatics

Sus antecedentes:

• Colorectal cancer (CRC) poses significant health risks, with inflammatory bowel disease (IBD) being a known risk factor.
• Understanding shared molecular mechanisms between IBD and CRC is crucial for developing effective early detection and prevention strategies.

Objetivo del estudio:

• To elucidate shared molecular mechanisms between IBD and CRC.
• To identify key proteins and regulatory pathways involved in colorectal carcinogenesis driven by inflammation.

Principales métodos:

• Proteomic analysis of UK Biobank data using Olink proximity extension assay for seven CRC-associated proteins.
• Comparison of protein expression levels in CRC and IBD cases versus controls.
• Construction of multilayer interaction networks (protein-protein, protein-metabolite, transcription factor-protein) using OmicsNet.
• Validation of findings using the Colonomics transcriptomic dataset.

Principales resultados:

• Seven CRC-associated proteins were analyzed; six were elevated in both CRC and IBD.
• Network analysis highlighted AHCY and LCN2 as central hubs connecting inflammatory and metabolic pathways.
• NF-κB and GATA2 were identified as recurrent transcriptional regulators.
• Colonomics data validated the upregulation of AHCY, LCN2, and SELE in CRC tissues.

Conclusiones:

• A shared molecular framework exists between IBD and CRC.
• Inflammation plays a pivotal role as a driver in colorectal carcinogenesis.
• The findings provide insights into potential therapeutic targets and biomarkers for CRC prevention and early detection in IBD patients.
